v1.0.7

Vivid 1.0.7

Highlights:

• Wallpapers no longer stay black on AMD GPUs whose drivers advertise DCC (multi-plane) DMA-BUF modifiers; the GNOME consumer used to reject every such buffer (#4).
• DMA-BUF negotiation now recovers by itself when a display consumer rejects a buffer pool, instead of requiring several wallpaper switches.
• Lower frame-publish latency: renderer relays are event-driven and NVIDIA video uploads no longer stall the GPU queue every frame.
• Scene renderer: interactive 3D perspective scenes, restored skinned models, particle overrides and cascade shadows, plus many fidelity fixes against Wallpaper Engine.

Display pipeline and DMA-BUF:

• GNOME consumer: identify DMA-BUF planes by device/inode instead of fd index, so non-disjoint multi-plane modifiers (AMD DCC) import through the Vulkan shadow relay.
• Producer: when a consumer reports BIND_FAILED for a renderer-owned pool, quiesce that worker and renegotiate against the updated modifier blacklist instead of blacklisting every remaining modifier and giving up with NO_DMABUF_SCHEME.
• Producer: a renderer worker that fails after publishing its buffers now releases that pool, so the next wallpaper no longer hangs in negotiation.
• Validate the exact fourcc/modifier/plane-count/usage tuple before creating export images in the video and web Vulkan backends, and stop advertising LINEAR capabilities the selected GPU cannot actually create.

Performance:

• Shared event-driven frame pump for scene, video and web workers: paused workers sleep instead of polling, and new frames wake the relay immediately.
• NVIDIA video path: CUDA<->Vulkan timeline semaphores, per-slot command buffers/fences and exported SYNC_FD acquire fences replace the per-frame cuStreamSynchronize and vkQueueWaitIdle.
• VA-API video path: copy decoded frames with vkCmdCopyImage when they match the export slot exactly.
• Scene renderer publishes offscreen frames without a per-frame CPU fence wait.

Scene renderer:

• Support interactive 3D perspective scenes (for example the solar system wallpaper).
• Restore skinned models, particle overrides and directional cascade shadows.
• Align layer visibility and render-target identity with Wallpaper Engine; defer the MSAA model-depth resolve.
• Keep pointer uniforms independent of camera-parallax delay; keep vertex-mode distortions and text effect finals in scene space.
• Fix padded spritesheet texture metadata and keep sprite image-card UVs in frame-local space.
• Give each particle instance its own emit runtime.
• Log a bounded first-frame stage trace after each render graph compile so worker crashes can be attributed to a specific render pass from the log.
• Internal: authored layer identity now lives on SceneObject, and the scene parser and script host are split into smaller units.

Tooling and documentation:

• Add a Chinese README and release installation instructions.
• Add golden-frame acceptance tooling and make tools/vivid.sh test run real tests; restore the standalone scene capture library and allow selecting its FPS.
• Fix release metadata and notes publishing in the release workflow.
